of lime used. 1. Flotation of copper at different pH is associated with the type of frother used. With certain frothers, copper recovery can be significantly increased at a lower pH range while some frothers need a higher pH to keep a more lasting frothing power.
In the quest of new, less hazardous, and more ambient-friendly froth flotation reagents, the use of biosolids or humic acids as both collector and frother for the concentration of copper sulphide ores was investigated. Rougher flotation tests were
Frothers may act to stabilize air bubbles so that they will remain well-dispersed in slurry, and will form a stable froth layer that can be removed before the bubbles burst. Ideally the frother should not enhance the flotation of unwanted material and the froth should have the tendency to break down when removed from the flotation apparatus.
Frothers used in galena flotation tend to be of the weaker type, such as MIBC, because galena is readily floatable and have high flotation kinetics. However, because of the high float kinetics and high galena mineral density, the mineral froth carrying capacity may necessitate use of a slightly stronger frother or a combination with a stronger ...

Jun 22, 2015 Froth Flotation Frothers are chemicals used to strengthen the SURFACE TENSION of an air bubble. They do not create air bubbles. To demonstrate surface tension, fill a glass of water just prior to over flowing, you will notice that the surface of the water actually extends past the lip of the glass. That is surface tension.
